Industrial 3-Port Gigabit + 1 SFP Fiber Ethernet Switch 12–48VDC
-40~75°C
Overview
The LNK-IMC103G-SFP is a rugged mini industrial Ethernet switch
featuring 3 Gigabit RJ45 ports and
1 dual-speed 100/1000X SFP slot. Housed in a compact IP40-rated
aluminum case, it supports a wide
temperature range from -40°C to 75°C, making it ideal for harsh
industrial environments. With flexible
SFP module options, DIN-rail/wall mounting, and energy-efficient
operation, this switch ensures reliable
connectivity for applications like IP surveillance, wireless
backhaul, and remote device networking.
